Be it known that I, MORRIS Kimi), a citi- Zen of the United States, and resident of Passaic, inthe county or" Passaic and State of New Jersey, have invented certain new and useful improvements in Machines i'or Testing Containers, of which the following 'is a specilication.

The lobject of niy invention is to provide i body is placed when 'upon rest 19. The rest- 10 may be adjusted along rod 9 by'ineans simple and efficient means for testing containers, such as cans and the like, under pneumatic pressure while immersed in Water, whereby if the containers leak the air bubbles coming` through the Water would indicate that fact.

My invention is particularly applicable to testing tin cans ai'ter the tops and bottoms have been soldered upon the same to ascertain it the cans have been properly to prevent leakage.

My invention comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out inthe'claims.

Reference is to be had to the accompany in drawings forming part hereof, wherein,

ltigure l is a plan View of a machine einbodying my invention;` Fig. 2 is partly sectional. side view, substantiallynon the plane lof the line 2, 2, in Fig. l, illustrating position to receive a cantor testing; Fig. 3 is a substantially similar vieu', illustrating the can immersed in a bath; Fig. 4 is an enlarged detail sectional View of the pneumatic head to be applied to the can opening; Fig. `5 is a sect-lepel detail view of the air cont-'rolling valve, and Fig. 6 is a vieweo the saine enlarged, talren on the plane of the line 6, 6, in Fig .3.

Similar numerals of reference indicate corresponding parte in the several views.

lit l is indicated a pipe or hollow support,

soldered which may be secured upon a table oi'tlie'V like 2, as upon the anged bushing or coupling 3, which pipe communicateswith any suitable source of air pressure, as the ,piping 4. At 5 is a rocker, shown in the form@ of a pipe or tube, and suitably extended' and provided with a weight Pim 5 ooininuni-=v cates with a valve 7 of any suitable construc-l Pipe 5 is shown tion fitted upon pipe l. fitted to the stem 7a of valve 7 by nieansor1 the hollow coupling 7b, the port Y, of the valve stem being so arranged as to close the passage to pipe 5 when the latter is raised,

i as in the position shown in Fig. 2,j and to open said passage when. pipe 5 is flowened,

upon permit air to ing a guide 8a receiving a sliding steni to the position shown iii Fig. Land therel dow thiough'said pipe@i llipe 5 is shown provided with a head 8 hav which is provided vnear its lower end .Witlijiif rest 10 for container ll. Rod 9 also earries a iorlror seat l2 against which the can of a screw 13, and the seat l2 may likewise accommodate cans or' different lengths. 8 has a pipe extension frl shown pr 0- vided with a head' 5i having a suitable noz. ale 5c adapted to enter an .opening ll in screwed into' the threaded end `of head 5b, and 'suitable packing 15 may be provided ad.- jacent said nozzle to engage the end of the can (see Fig. 4). The rod is to be opera-ted to hold and release theA cans when the same are to be charged with air under pressure. .F or this purpose l have shown a lever 16, pivotally supported at 17 upon an extension 18 from head 8, the end 16a of said lever entering guide 8L through a slot 8f therein and engaging in s slot or recess 9a in rod 9. Lever 15 is shown connected by a rod 19 1with a treadle 2O normally pressed upwardly by spring 2]'. shown connected with said` treadle and With table 2. A stop 190L Von rod 19 by engaging table 2 serves to limit the downward movement oi' the above described parts. v l Beneath head 8 and rod 9 Ais a suitable tank or receptacle 22 shown supported by v table 2 and adapted to receive Water or other suitable fluid. lilith the parts in the posi tion shown in Fig. 2, the can or container l1 may be placed by the operator upon rest i() and against seat 12 and then the treadle 'ing lever 16, whereupon rod 9 is raisedl and theccan opening or neck 11j? isv pressed againstwasher 15, andnozzle "5 enters the can, forming a substantially air tight'llt.` A.- further y'ile-.viiWard` movement iof ythe treadle causes ythe parts to bind together in such nia-nner that the can and head 5 are 22, the pipe 5 thereupon 'rockingto such lowered position, and valve stern 7 is thus turned in such position that air 4will ildw can il. Nozzle cinay be formed on a disk` be adjusted along rod 9 by a screw 14.1 fto .is depressed, pulling down rod '19 and 'rock` I caused to be immersed in the Water in tank water 'will disclose that fact.V yWVhen the treadle is released Ithe parts return'to their i normal positions 2) shutting o the vio .applicable to testing -hollow ticles other 4than tin cans,

air supply and releasing the can, and1s-o on for further testing o cans. v

It will be understood that m `invention is dies or di and whether the parts are soldered together or secured together by other means,`

tegral. lAlso thatfchanges may be made in the arrangements of parts set forth, within the scope of the appended claims, Without departing from the spirit of my invention.

Having now described my invention what I claim is i 1. The combination of .a tubular support provided with an air outlet, means connected with said support to clamp a container against said outlet, and simultaneously depress the support and container and a valve connected with said support to `permit the loiv of air therethrough to the container when in one position and prevent the lflow of air therethrough When in another position. 2. The combination ot' a holloiv pivoted support provided with a head having an air outlet, means connected with said support to clamp a container' against said outlet, a valve to eonimunicate ivith said hollow supyport to control the flow of air through said support as the latter rocks, an operating member, and meaiisconnecting said member with said clamping means to simultaneously operate the latter and vdepress said support thereby. I .Y u i 3. The ciiinbination of a valve having a rocking stein, a pipe connected with said stem to receive compressed tliiid therefrom 4and provided with a head havingl an outlet,

container damping means 4carried by said pipe to clamp a container against said head, and means for operating said clamping means and rocking said pipe simiiltaneously.y

4. The coi'nbination of a pipe having a head provided with an air outlet, means to control the How vof air through saidpipe, a rest for a container movablycarric'd by said pipe 'to clamp the container against said head, and means to l'raise said restv toward said head and'simultaneously rock the same and the pipe downwardly.

The combination `of ay valve having a stein, a pipe connected with said stem, a

head connected with said pipe and ha ing and the bubbles rising through theA V6'. The combination `porting means carried or are formed in-l an air outlet, aguide carried by said pipe, a rod carried b said guide, means for hol' ing a container against sai head, a lever carried by said pi e and operatively connected withlsaid ro and means to operate against the head and de ress the same.l
